Join Todd Perkins for an in-depth discussion in this video Viewing the finished app, part of Building a Calculator for Apple Watch.
- Here is the final version of the app we're going to build in this course. If I click on the icon from the Watch home screen, it launches the application. The app is a simple calculator with a plus, minus, clear, and equals button. You can tap in a number, tap the plus or minus button, tap another number, and that second number appears, press the equals button to see the result. So we can add or subtract, and then we can clear the calculator by pressing the clear button.
The calculator also formats numbers, so in this case a comma is shown as I add extra numbers. This app is built entirely from scratch. We'll look at how to style the user interface elements and how to lay them out, and how to write all the application logic throughout the course.
